Ocular implant systems
DCFirst Claim
1. An ocular implant system for draining aqueous humor to a uveoscleral outflow path of an eye, comprising:
- an ocular implant, the ocular implant comprising an elongated body, the elongated body including;
an inlet port arranged on a proximal end segment of the ocular implant to communicate with an anterior chamber of an eye;
an inner lumen communicating with the inlet port; and
at least one outlet port in communication with the inner lumen; and
an applicator preloaded with the ocular implant, the applicator including;
a handpiece having a proximal end and a distal end;
an elongated member coupled to the distal end of the handpiece, the elongated member being sized to pass through an incision in the eye and into the anterior chamber of the eye and to facilitate ab interno insertion and advancement of the ocular implant into an anterior chamber angle and then to an implantation location in uveal tissue of the eye,wherein the elongated member has a sufficient length so as to extend from the incision into the anterior chamber to the implantation location in uveal tissue,wherein the elongated member comprises a curved distal end portion that engages the ocular implant in a coaxial manner; and
a deployment mechanism configured to act upon the ocular implant, the deployment mechanism and the elongated member being movable relative to each other so as to deploy the ocular implant from the elongated member and into the implantation location in uveal tissue.

Abstract
Implants and methods for treating ocular disorders are disclosed. One implant has a tubular member, with inlet and outlet ends, and a cutting member connected thereto. The tubular member is configured to extend through eye tissue such that the inlet and outlet ends reside respectively in an anterior chamber and a physiologic outflow pathway of the eye. Desirably, the cutting member is configured to make an incision in the eye tissue for receiving at least a portion of the tubular member. One method involves introducing an implant, with proximal and distal ends, into the anterior chamber and penetrating eye tissue using an implant distal portion. The implant is advanced from the anterior chamber into the penetrated eye tissue to locate the distal and proximal ends respectively in the physiologic outflow pathway and the anterior chamber. Aqueous humor is conducted between the proximal and distal ends.

16. A system for implanting an ocular implant to drain aqueous humor from an anterior chamber of an eye to a uveoscleral outflow route of the eye, the system comprising:
-
an ocular implant, the ocular implant comprising a tubular body, the tubular body including; an inlet port arranged on a proximal end segment of the ocular implant to communicate with an anterior chamber of an eye; an inner lumen communicating with the inlet port; and at least one outlet port in communication with the inner lumen; and an applicator preloaded with the ocular implant, the applicator comprising; a handpiece; and an elongated member extending from the handpiece, the elongated member being configured to be placed into the anterior chamber of the eye and to facilitate ab interno insertion and advancement of the ocular implant to an implantation site in uveal tissue of the eye such that, when implanted, the ocular implant resides entirely within the confines of a cornea and a sclera of the eye, the elongated member further comprising a curved distal end portion configured to deliver the ocular implant to the implantation site, wherein the ocular implant and at least the curved distal end portion of the elongated member are positioned about a common axis before implantation. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)

25. A system for implanting an ocular implant to drain aqueous humor from an anterior chamber of an eye to a uveoscleral outflow route of the eye, the system comprising:
-
an ocular implant including an inlet port, an outlet port, and a lumen extending between and communicating with the inlet port and the outlet port; and a delivery device configured to advance the ocular implant from within the anterior chamber using an ab interno procedure, the delivery device advancing the ocular implant with the outlet port leading the inlet port and having a curved configuration at a distal end portion while advancing the ocular implant. - View Dependent Claims (26, 27, 28, 29, 30, 31)
